Title: How to repair a garage door - PowerPoint PPT Presentation

Description: There are two main components to a garage door: the door itself and the opener.Overhead garage doors, whether they roll up in sections or swing up in one piece, operate on spring tension. The door moves on metal tracks on the garage walls, and a heavy spring or springs provide the power.Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. – PowerPoint PPT presentation
